ALUMINUM-AIR POWER-CELL SYSTEM DESIGN

The reaction of Al with water and air in NaOH electrolyte is an electro-chemical system being developed as a possible source of automobile propulsion. The Al-air cell is a small part of a large power-cell system. In addition to concerns of reactant supply and product removal, various separation and thermal-management problems in the overall system must be solved. Five subsystems support the operation of the Al-air cell: air, electrolyte, hydrargillite, water, and coolant. A computer program was written to calculate the flowrate, chemical composition, and temperature of each stream. Four parameters (oxygen stoichiometric factor, current density, temperature of entering air, and temperature of crystallizer for Al(OH) sub 3 were varied to measure system response, and the results are presented. 5 figures, 2 tables.
